9.(SBAC)This graph shows the relationship between the amount of money in Angelo’s savings account and the number of weeks Angelo has been saving money. He started with $10 in his account. Select the statement that correctly reflects what is shown in the graph.

1. The slope of the line is , so Angelo’s savings rate is $14 every week.
2. The slope of the line is , so Angelo’s savings rate is $1 every 14 weeks.
3. The slope of the line is , so Angelo’s savings rate is $4 every week.
4. The slope of the line is , so Angelo’s savings rate is $1 every 4 weeks.

10.(SBAC F2) Marcie and Kiah wrote down two different functions that have the same rate of change. Marcie’s function is represented by the table shown.

12.(SBAC F2) Consider this graph of the line. Which equation has a rate of change greater than the rate of change for the line shown?

13.(SBAC F2) A small swimming pool has 42 gallons of water in it. To fill it, water is added at a rate of 6 gallons per second. Select the equation that models the relationship between the amount of water (W), in gallons, in the swimming pool after the amount of time (t) seconds.

A.

B.

C.

D.

14.(SBAC F2) The table and equation shown each represent a different linear function.

x / y
-3 / 0

What is the difference between the rates of change for these two functions?

15.(SBAC F2) The table shows the relationship between the monthly cell phone cost for Plan A and the number of minutes used within a month.

Cell Phone Cost for Plan A
Time (min) / Cost (dollars)
0 / 30.00
2 / 30.20
4 / 30.40

The following equation shows the relationship between the monthly cell phone cost (c)in dollarsfor Plan B and the number of minutes used with a month (m).

The flat rate is defined as the monthly cost for the phone when zero minutes are used. What is the difference, in dollars, between the flat rate for Plan B and the flat rate for Plan A?
